Where Is This?

Does anyone recognize this location? It appears to be a quarry of some sort. The sign on the building reads "American Aggregates Corporation." The second line may give a location but it is difficult to read. The photo is from the 1940's.

Thanks to Mike, Mikem and Anonymous for their contributions in identifying the quarry as being located in Oxford, Michigan. The quarry still exists today and is used for gravel mining. At one time, Oxford billed itself as “The Gravel Capital Of The World.”
